Linux监控 Nagios

發布時間：2025/3/18 linux 34 豆豆

生活随笔收集整理的這篇文章主要介紹了 Linux监控 Nagios 小編覺得挺不錯的,現在分享給大家,幫大家做個參考.

Linux監控 ?

Nagios ?

1 什么是監控？監視控制

2 監控誰？ ???????各種服務器

3 監控什么？ ????網絡流量(eth0,eth1) ??服務的狀態（運行，停止） ?硬件資源 cpu ?內存存儲 ???

??????????????????????????系統運行情況(總數，運行，休眠，僵尸） ??

[root@room1pc01 桌面]# uptime

?09:15:02 up ?15min, ?4 users, ?load average: 0.01, 0.10, 0.08

??????????????????(數越大，說明在線時間越長，越好）

[root@room1pc01 桌面]# top ?（看cpu)

4 如何監控？ ???使用命令 ??編寫腳本 ????監控軟件

自動監控：

計劃任務+監控腳本（chkconfig crond on)

搭建監控服務器(軟件 ?Nagios ?Cacti ?Zabbix)

5如何接收報警信息（郵件，短信，微信，即時消息）

++++++++++++++++++++++++++++++++

配置監控服務器的步驟：

1. ?部署服務運行環境 httpd(nginx或Apache，php) yum -y install httpd php

2. ?安裝提供服務的軟件

2.1 安裝準備

2.2 安裝監控服務軟件和監控插件軟件

2.3 修改服務配置文件

2.4 啟動監控服務

3. ?配置監控服務

3.1 配置監控遠端服務器

3.2 配置監控自己（特殊情況,公司小只有一個網站服務器時，網站和監控服務配在一臺上，所以監控本機網站）

不監控本機的交換分區

監控引導分區的使用情況

監控ftp的運行狀態

指定接收報警信息的郵箱地址是nagios@localhost

4 ?配置監控報警

5 ?查看監控信息

設置查看訪問監控頁面的認證用戶名和密碼（不能隨便指） nagiosadmin

nagios服務的監控過程：服務運行時調用插件，調用插件時，可以設置插件監控的閥值，nagios服務把監控到的值和插件指定的值比較，根據比較結果顯示監控狀態》

插件監控的閥值種類：警告值錯誤值（值的多少由運維人員指定）

監控狀態： ?ok正常 ?warning警告狀態 ?critical 嚴重錯誤 ??unknow配置錯誤 ?pending正在監控

監控到的數據小于警告值顯ok ??大于警告值且小于錯誤值顯示warning ???大于錯誤值顯示critical

nagios服務默認監控本機哪些資源？

cpu負載

登錄系統總用戶數

網站服務運行狀態

主機是否在線

跟分區使用量

sshd服務運行狀態

[root@99 libexec]# ./check_users -h （每個插件都會提供幫助）

TCP OK - 0.000 second response time on port 22|time=0.000243s;;;0.000000;10.000000

____修改服務配置文件可以自己增加監控服務（先增加監控本機服務）_____________________

[root@99 nagios-3.2.1]# ls /usr/local/nagios

bin ?etc ?libexec ?sbin ?share ?var

libexec:插件目錄

bin:可執行命令

etc:配置文件

sbin:cgi文件（點監控頁面時出現的各種頁面）

var:變化的，日志緩存

share:配置文件

nagios服務配置文件說明？

[root@99 nagios]# ?/usr/local/nagios/bin/nagios -v /usr/local/nagios/etc/nagios.cfg ??（檢查配置文件是否有錯）

[root@99 nagios]# vim /usr/local/nagios/etc/nagios.cfg

??19 log_file=/usr/local/nagios/var/nagios.log

??30 cfg_file=/usr/local/nagios/etc/objects/commands.cfg ?（設置服務運行時使用的監控插件）

??31 cfg_file=/usr/local/nagios/etc/objects/contacts.cfg ???（設置接收報警消息的郵箱地址）

??32 cfg_file=/usr/local/nagios/etc/objects/timeperiods.cfg ??（定義監控時間模板的文件—）

??33 cfg_file=/usr/local/nagios/etc/objects/templates.cfg ????（定義監控模板的配置文件）

?36 cfg_file=/usr/local/nagios/etc/objects/localhost.cfg ?????（這個文件監控本機的配置文件，是里面的內容容器導致，不是文件名可以隨變）

/usr/local/nagios/etc/resource.cfg 宏定義 ??$USER1$(插件定義目錄)

_______________________

[root@99 ~]# vim ?/usr/local/nagios/etc/objects/commands.cfg ?（設置增加監控服務使用的插件）

define command {

????????command_name monitor_localhost_boot

?????????command_line ?/usr/local/nagios/libexec/check_disk -w 20% -c 10% ?-p ?/boot

} (這四行和下面四行只要寫一個就行。這用的是常量，下面變量）

define command {

????????command_name monitor_localhost_boot

?????????command_line ?/usr/local/nagios/libexec/check_disk -w $ARG1$ -c $ARG2$ ?-p ?$ARG3$

}

define command {

?????command_name monitor_localhost_ftp

?????command_line $USER1$/check_ftp -H localhost -p 21

}

2）設置接收報警消息的郵箱地址

[root@99 nagios]# /etc/init.d/postfix status

master (pid ?1766) 正在運行...

[root@99 ~]# vim /usr/local/nagios/etc/objects/contacts.cfg （設置接收報警消息的郵箱地址，先郵件服務開啟，如果設置的是163，一定要先能163能接收到）

3）定義監控時間模板的文件

[root@99 ~]# vim /usr/local/nagios/etc/objects/timeperiods.cfg

?28 define timeperiod{

?29 ????????timeperiod_name 24x7

?30 ????????alias ??????????24 Hours A Day, 7 Days A Week

?31 ????????sunday ?????????00:00-24:00

?32 ????????monday ?????????00:00-24:00

?33 ????????tuesday ????????00:00-24:00

?34 ????????wednesday ??????00:00-24:00

?35 ????????thursday ???????00:00-24:00

?36 ????????friday ?????????00:00-24:00

?37 ????????saturday ???????00:00-24:00

?38 ????????}

?39

?40

?41 # 'workhours' timeperiod definition

?42 define timeperiod{

?43 ????????timeperiod_name workhours

?44 ????????alias ??????????Normal Work Hours

?45 ????????monday ?????????09:00-17:00

?46 ????????tuesday ????????09:00-17:00

?47 ????????wednesday ??????09:00-17:00

?48 ????????thursday ???????09:00-17:00

?49 ????????friday ?????????09:00-17:00

?50 ????????}

4）定義監控模板的配置文件

[root@99 ~]# vim /usr/local/nagios/etc/objects/templates.cfg

5）（這個文件監控本機的配置文件，是里面的內容容器導致，不是文件名，文件名可以隨變起）把增加的監控本機的服務寫在監控本機配置文件中（在底下寫）

[root@99 ~]# vim /usr/local/nagios/etc/objects/localhost.cfg

define host{

????????use ????????????????????linux-server ???????????; Name of host template to use

; This host definition will inherit all variables that are defined

; in (or inherited by) the linux-server host template definition.

????????host_name ??????????????localhost

????????alias ??????????????????localhost

????????address ????????????????127.0.0.1

????????}

define service{

????????use ????????????????????????????local-service ????????; Name of service template to use

????????host_name ??????????????????????localhost

????????service_description ????????????PING

????????}

.........................

##################################myset################################333

define service{

????????}

[root@99 nagios]# ?/usr/local/nagios/bin/nagios -v /usr/local/nagios/etc/nagios.cfg 測試配置文件語法是否有錯

6）設置訪問cgi配置用戶

[root@99 nagios]# cd /usr/local/nagios/sbin/

[root@99 sbin]# ls

avail.cgi ??extinfo.cgi ???????outages.cgi ?statuswml.cgi ?tac.cgi

cmd.cgi ????history.cgi ???????showlog.cgi ?statuswrl.cgi

config.cgi ?notifications.cgi ?status.cgi ??summary.cgi

[root@99 etc]# vim /usr/local/nagios/etc/cgi.cfg ??設置訪問cgi配置用戶

119 authorized_for_system_information=nagiosadmin ?（登錄的用戶名）

[root@room1pc01 桌面]# http://192.168.4.99/nagios 在瀏覽器中再點server刷新一下等幾分鐘會再增加監控的服務

[root@99 sbin]# vim /usr/local/nagios/etc/nagios.cfg ??????（1.在nagios主配置文件中，寫上監控服務器的文件名，起服務會自動加載這）

??36 cfg_file=/usr/local/nagios/etc/objects/localhost.cfg (監控本機）

??37 cfg_file=/usr/local/nagios/etc/objects/otherser.cfg ?（監控遠程的主機）

[root@99 objects]# vim /usr/local/nagios/etc/objects/otherser.sh ?(2.寫容器定義監控遠端主機的哪些服務）

DISK OK - free space: / 42137 MB (92% inode=97%);| /=3215MB;23893;33450;0;47786

2 ?在被監控的主機上運行nrpe服務

#useradd ?nagios

#rpm ?-q openssl ??openssl-devel

#tar -zxvf nrpe-2.12.tar.gz

#cd nrpe-2.12

#./configure

#make all

#make install-plugin

#make install-daemon

#make install-daemon-config

#make install-xinetd

#vim /etc/xinetd.d/nrpe

# /etc/init.d/xinetd restart

驗證nrpe命令(192.168.4.98)

/usr/local/nagios/libexec/check_nrpe -H localhost -c ?check_nrpe_root

4.在監控服務器上配置（192.168.4.99）

#/usr/local/nagios/libexec/check_nrpe -H 192.168.4.98 ??-p 5666 ?-c ?check_nrpe_users ?(報錯，沒那個目錄）

1）安裝依賴包

# yum -y install openssl openssl-devel

2）

# tar -zxvf ?nrpe-2.12.tar.gz

# cd nrpe-2.12

#./configure

?#make all

#make install-plugin

?#ls /usr/local/nagios/libexec/check_nrpe

3）在命令行下測試

# /usr/local/nagios/libexec/check_nrpe -H 192.168.4.98 -p 5666 -c check_nrpe_users

USERS OK - 2 users currently logged in |users=2;2;5;0

# /usr/local/nagios/libexec/check_nrpe -H 192.168.4.98 -p 5666 -c check_nrpe_load

OK - load average: 0.00, 0.00, 0.00|load1=0.000;15.000;30.000;0; load5=0.000;10.000;25.000;0; load15=0.000;5.000;20.000;0;

4）把連接nrpe服務的插件定義成nagios服務可以使用的監控命令

# vim /usr/local/nagios/etc/objects/commands.cfg

...............................

define command {

?????command_name monitor_server98_boot

?????command_line $USER1$/check_nrpe -H 192.168.4.98 -p 5666 -c check_nrpe_boot

}

define command {

?????command_name monitor_server98_load

?????command_line $USER1$/check_nrpe -H 192.168.4.98 -p 5666 -c ?check_nrpe_load

}

define command {

?????command_name monitor_server98_users

?????command_line $USER1$/check_nrpe -H 192.168.4.98 -p 5666 -c ?check_nrpe_load

}

define command {

?????command_name monitor_server98_root

?????command_line $USER1$/check_nrpe -H 192.168.4.98 -p 5666 -c ?check_nrpe_root

}

define command {

?????command_name monitor_server98_zombie

?????command_line $USER1$/check_nrpe -H 192.168.4.98 -p 5666 -c ?check_nrpe_zombie_proc

}

define command {

?????command_name monitor_server98_total_procs

????command_line $USER1$/check_nrpe -H 192.168.4.98 -p 5666 -c ?check_nrpe_total_procs

}

5)在監控主機配置文件中調用定義的監控命令

# vim /usr/local/nagios/etc/objects/otherser.cfg

#################################private###########################

define service{

????????use ????????????????????????????local-service

????????host_name ??????????????????????server98

??????service_description ????????????users

????????check_command ??????????????????monitor_server98_users

}

define service{

????????use ????????????????????????????local-service

????????host_name ??????????????????????server98

????????service_description ????????????root

????????check_command ??????????????????monitor_server98_root

}

define service{

????????use ????????????????????????????local-service

????????host_name ??????????????????????server98

????????service_description ????????????total_procs

????????check_command ??????????????????monitor_server98_total_procs

}

define service{

????????use ????????????????????????????local-service

????????host_name ??????????????????????server98

????????service_description ????????????boot

????????check_command ??????????????????monitor_server98_boot

}

define service{

????????use ????????????????????????????local-service

????????host_name ??????????????????????server98

????????service_description ????????????load

????????check_command ??????????????????monitor_server98_load

}

define service{

????????use ????????????????????????????local-service

????????host_name ??????????????????????server98

????????service_description ????????????zombie

????????check_command ??????????????????monitor_server98_zombie

}

6)測試配置文件是否有語法錯誤

# alias plj='/usr/local/nagios/bin/nagios -v /usr/local/nagios/etc/nagios.cfg'

# plj

7)重啟監控服務

# /etc/init.d/nagios restart

8)查看監控信息
